Abstract: A satellite radio receiver obtains signals from a satellite receiving installation comprising one or more frequency converters which may, for example, undergo a frequency drift as a result of temperature variations which cannot be compensated by an AFC circuit which is located in the satellite radio receiver and which controls a carrier oscillator for carrier regeneration in a demodulator circuit. According to the invention, a local oscillator for a mixer is designed as a PLL local oscillator (44) which can be tuned in a large or a small increment. The AFC circuit (1) and a synchronizing signal evaluation circuit (40) are corrected to a control circuit (34) by means of which the PLL local oscillator (44) is tuned, outside the control range of the AFC circuit (1), with a large increment in the case of undetected synchronizing signals and with a small increment in the case of detected synchronizing signals until the control range of the AFC circuit (1) is reached. The satellite radio receiver described is suitable for connection to satellite receiving installations which comprise a plurality of frequency converters and therefore deviate the nominal receiving frequency in a summary fashion and for private individual installations which, for economic reasons, possess low frequency stability.
